It could have to do with all the trading hype of 4-5 years ago. Most of those who entered that time got killed in the Naz bubble and decimalization bang.

Those who have been trading for over 5 years were experienced enough, and prepared to see it all coming, survive and adapt.

Those who started 3 years ago basically were rats to evolve after the post-decimalization-and-bubble-burst holocaust, born under the most cruel conditions, genetically modified to withstand and co-exist within bearish radiation, while the pretty new white mice of 1999 got irradiated till the bleeding tumors of bull-market amateurism burst. The new generation started and evolved expecting the worst. LOL that even rhymes.
